MILK ALLERGY

[摘要] In a series of 172 infants under 2 years of age who were referred for allergy studies during 1954-1956, 109 were found to be allergic.Thirty-three of the one hundred nine allergic infants were sensitive to cow's milk, with an incidence of 30%.The diagnosis of cow's milk allergy was based upon the same criteria applied to a series of well babies. Namely, repeated production of one or more allergic symptoms on exposure to cow's milk, improvement on withdrawal, and with no other apparent cause for improvement, confirmed by positive skin test, and without other cause for symptoms.The allergic symptoms due to milk were eczema, gastrointestinal abnormalities and less frequently asthma or rhinitis.Scratch tests were frequently positive to foods. Thirty-seven infants reacted with positive skin tests to milk, of whom 33 had clinical allergy to milk. Infants from 9 to 12 months of age had the highest number of nonspecific skin reactions.
